研究方向

Investigate the config package in the IPFS Go repository, specifically how config values are read and written. The issue occurs because large integers (e.g., 1048576) are being serialized in Go's default JSON marshaler using scientific notation (1.048576e+06), which then fails to unmarshal into an int type. Look at the config structs and how they handle numeric fields. Consider using json.Number or implementing a custom unmarshaler to preserve integer precision. Check comments in the issue for any pointers, and search for similar fixes in the codebase.
